Raised Pavement on Danville Blvd heading North @ Twelve Oaks Court

description

Heading north on Danville Blvd from Livorna just before the intersection with Twelve Oaks Court there is a bump with a crack across the bike lane, I believe it is caused by a large tree root.
Unfortunately, today I was riding with a group of four or five bicycle riders and was pitched off my bicycle, luckily just suffering a few scrapes and bruises.
The addresses for Twelve Oaks Court are in Alamo so I'm not exactly sure of the appropriate jurisdiction.
It would great if the 'bump' in the bike lane could be removed or at a minimum put paint in the bike lane to warn riders before someone suffers a more serious injury.
Thank you.
Sincerely,
Pete Culshaw
Update 8-30-17: CoCoCo PW responded immediately to the Bike East Bay hazard notice and sent someone out immediately: "Thank you for bringing this pavement condition to our attention! A crew
ground down the raised up pavement location and filled and patched the
cracked portion. We will keep an eye on the location, but if you or members
of you group observe any additional cracking or raised up pavement, please
let us know." And Thanks, Pete, for going out and checking on their work!
